Leopoldo Nachbin

Nachbin Leopoldo ( born January 7, 1922 in Recife, † April 3, 1993 in Rio de Janeiro) was a Brazilian mathematician who was concerned with functional analysis and topology. He was one of the founding members of the Instituto de Matemática Pura e Aplicada.

His father Jacob was a Nachbin Jewish immigrants from Poland, who published a Yiddish newspaper in Rio and disappeared as a journalist in the Spanish Civil War in 1936. His mother Léa Drechter came from Austria. Nachbin went to school in Recife and was originally Engineer ( completion in 1943 as a civil engineer at the Engineering School of Rio). He studied at the University of Rio mathematics at the Italian mathematicians Gabriele Mammana ( a student of Mauro Picone ) and Luigi Sobrero ( a student of Tullio Levi -Civita ) and in 1948 its free lecturer (corresponding to the promotion ) with the dissertation Combination of metrizable and non- metrizable Topologies. He was in 1948 one of the first Brazilian mathematicians who went to an American university at the University of Chicago. Here he established contacts with André Weil, Jean Dieudonné and Marshall Stone, who were then in Chicago and visited Brazil, as well as Laurent Schwartz. He was in the 1950s and early 1960s as the most important mathematicians of Brazil. He was a professor at the University of Rio and from 1964 at the University of Rochester, although he retained his professorship in Rio. He was a cosmopolitan with many international contacts and took many visiting professorships in Europe and America was, for example, in Paris ( such as the Institute Henri Poincaré ), the Institute for Advanced Study ( 1958), at Brandeis University and the University of Chicago.

According to him and Edwin Hewitt Nachbin -Hewitt rooms are named.

He dealt with topological orders, topological vector spaces, harmonic analysis, general topology, approximation theory and holomorphy in infinite dimensional spaces. He has published in Portuguese, French and later mainly in English.

In 1967 he founded with Heitor Gurgulino de Souza, the Escola Americana de Matematica Latino. He was from 1948 Notas de Matemática editor of the ( until 1976 at IMPA and then at North Holland, Amsterdam ).

In 1962 he was invited speaker at the International Congress of Mathematicians in Stockholm ( result recents et problemes de nature algébrique s theory de l' approximation).

In 1962 he received the Moinho Santista price ( the first mathematician in Brazil). In 1982 he was awarded the Bernardo Houssay Award of the Organization of American States.

He was married in 1956 to Maria da Graça Mousinho, with whom he had two sons and a daughter. A son is the Brazilian journalism professor and TV host Luis Nachbin (* 1964). Another son André Nachbin is also a mathematician.

He was a member of the Brazilian Academy of Sciences (1950) and the Latin American Academy of Sciences at its founding in 1963.
